When Overflow of DataTypes occur in Java

When a value more than the Maximum value of a datatype is assigned, it leads to Overflow. Java handles overflow of  datatypes on its own, for example, if we will increment 1 to Integer.MAX_VALUE, an error won’t be visible. However, the output will be Integer.MIN_VALUE.

Let us now see some examples displaying how Java handles overflow of datatypes:

Example 1

The code shows how Java handles overflow of int datatype:


Example 2

The code shows how Java handles overflow of long datatype:


However, this is not the case with any other datatype. Let’s see another example wherein we are multiplying the Maximum value of Float type:

Example 3


In the above output, we are getting Infinity i.e. Overflow since we exceeded the maximum value of Float Datatype in Java.
